Video description:
A melanoma expert from NYU Langone, Jeffrey Weber, MD, PhD, describes how immunotherapy works with your body’s own immune system to kill tumor cells, and how this type of treatment has helped patients with later stages of melanoma. He discusses how checkpoint inhibitors and other immune system drugs work and how these drugs may work better when combined with each other. In melanoma, checkpoint inhibitors block proteins called PD-1 and CTLA-4. Several other kinds of immunotherapy drugs may also be used to treat melanoma.
